Seamless Integration: Telstra NB-IoT Network and Telemetry2U

Telstra NB-IoT Coverage Map

Telemetry2U is excited to announce the integration of Dragino's innovative NB-IoT products into our IoT platform. Dragino, a leader in reliable IoT hardware, has made device configuration easier than ever. Most of their new NB-IoT and LoRaWAN devices now feature a Bluetooth module, allowing for quick and effortless setup via a smartphone.

In Australia, we utilise Telstra's robust NB-IoT network to its full potential. Our SIM cards, starting at just $2.50 per month for 500kB of data, are typically sufficient for transmitting an uplink every 5 minutes.

For those who purchase Dragino NB-IoT hardware directly from Telemetry2U, we offer the convenience of pre-installing a Telstra NB-IoT SIM card and pre-configuring your device. This means your new device is ready to be added to the platform right out of the box. And for those who have sourced their hardware elsewhere, worry not - integrating it with our platform is straightforward. Simply follow the easy hardware configuration steps provided below.

Configuring NB-IoT Device's via Bluetooth

If you didn't purchase your NB-IoT device from Telemetry2U, don't worry - setting it up is straightforward. Just follow these easy steps:

  1. Acquire an IoT SIM Card: For users in Australia, we recommend Telstra NB-IoT SIM cards for optimal performance. However, any NB-IoT enabled SIM card will suffice. Remember to set the APN according to your network provider.
  2. Install the SIM Card: Insert the SIM card into your Dragino device as outlined in the Dragino documentation. Ensure the contacts face the PCB and the tab points outward for a correct fit.
  3. Power Up Your Device: Press and hold the button on your Dragino NB-IoT device for 5 seconds to turn it on. Allow a couple of minutes for it to fully boot.
  4. Download the Serial Bluetooth Terminal App: This app is available for Android devices and is essential for the next steps.
  5. Connect via Bluetooth: Launch the Serial Bluetooth Terminal App and go to 'Devices >> Bluetooth LE'. Select your Dragino device from the list to connect.
  6. Enter the Device PIN: Input the PIN for your Dragino device, which you can find on its packaging, to authenticate the connection.
  7. Send the following commands: This will configure the NB-IoT devices to work on Telemetry2U using the Telstra NB-IoT network

AT+SERVADDR=,4483 - Configures the server address and port to work on Telemetry2U's server

AT+APN=telstra.iot - Configures the APN to work on the Telstra NB-IoT network.

AT+QCGDEFCONT="IPV4V6","telstra.iot" - Set the BC660K-GL's default PSD connection settings.

AT+CGDCONT=1,"IPV4V6","telstra.iot" - Define the BC660K-GL's PDP context

AT+QBAND=1,28 - Sets the modems band to '28' as used by the Telstra NB-IoT network.

ATZ - Resets the Dragino NB-IoT device. It will not connect to Telemetry2U at this stage as it still needs to be added on the T2U platform.

AT+CFG - Confirm the settings are the same as described above and while you're here, make a note of the 8-Byte(HEX) DEUI as this will be required in the next steps.

And that’s it! These simple steps will get your device up and running on our Telemetry2U servers in no time.


By default, most Dragino NB-IoT devices will send 8 records in a single uplink every two hours to conserve power and extend battery life. The default factory settings and their functions are explained below.

AT+NOUD=8 - The number of packets to send during an uplink.

AT+TDC=7200 - How often an uplink will be sent.

AT+TR=900 - How often reading are recorded.

If you would like to send a single record every uplink (every 30 minutes for example), you could use the setting below.

AT+NOUD=1 - Send one packet per uplink.

AT+TDC=1800 - Send an uplink every 30 minutes.

AT+TR=65535 - Log a record to memory at the maximum allowable interval.

Adding NB-IoT Device's to Telemetry2U's Platform

Now that you've properly configured your Dragino NB-IoT device, you can add it to the Telemetry2U platform. First, ensure you have a free Telemetry2U account set up. If not, please create one, it doesn't tke long. Then, follow these simple steps to add your Dragino NB-IoT device:

  1. Navigate to Node Management: Go to 'Admin >> Node Maintenance' and click on the 'Add New Node' button.
  2. Choose Your Network: Select 'NB-IoT over UDP' as the network provider.
  3. Device Configuration: Pick the correct configuration for your device from the provided list.
  4. Assign a Unique Description: Give your new device a distinctive description for easy identification.
  5. Enter the Device IMEI: Input the IMEI number of your new device into the IMIE field. It should be 15 characters in length.

After completing these steps, reset your Dragino NB-IoT device by holding down its button for over 5 seconds. It should successfully connect to Telemetry2U within a few minutes.


If you have successfully connected your Dragino NB-IoT device to Telemetry2U, data should appear on the Reports page. If you don't see any data after a few hours, please use the Bluetooth connection revisit the device's configuration settings to ensure they are correctly configured as described above.

Should the data from your Dragino NB-IoT device appear unclear or inconsistent, check the device settings on the Node Maintenance page to confirm that the correct device configuration is selected.

Creating a Real-Time NB-IoT Dashboard on Telemetry2U

Creating dashboards on Telemetry2U is straightforward, though currently, they can only be set up on a PC. Log in to Telemetry2U on a PC and simply follow these steps:

  1. Start a New Dashboard: On the Dashboard page, use the “Create New” button at the top to begin.
  2. Enter Editing Mode: Click the 'Editing' button to access a variety of widgets in the new menu.
  3. Add Widgets: Select a widget by left-clicking, then drag and resize it on the canvas using the arrow in the bottom right corner.
  4. Configure Widget Settings: Double-click a widget to choose its node, input, style, and set min/max values.
  5. Save Your Dashboard: Click 'Save' in the editing menu once you're done.

Sharing Options: To share with all users in your account, tick the 'Company Wide' box. Or, assign the dashboard to specific users with the 'Copy Dashboard' function via the Admin section.
